WIRE ROPE.

To lall whomfit vmay concern .i

' 'Be it known that I, TELFoRD CLARENCE BATCHEEOR, a subject of the King of Great Britain, residing at Hay Mills, nearv Birmingham, England, have invented certain new and useful Improvements in Wire Ropes, of which the following is a specifica- 'tion. f

The present invention relates to improve'- ment's in wire ropes, and it has for its object primarily to provide a stranded rope containing a-relatively large area of effective l vwire with corresponding degreeof strength as compared with other ropes as heretofore constructed and containingthe same guan- .tity and quality of material, to provlde a rope whichI wi l be, non-spinning, and one in which the internal friction is reduced to a According to this invention I take what is known as a locked coil wire rope and I cover same with one or more concentric layersof attenedor other strands of wire, the attened or other strands each comprising a plurality of wires twisted together and being coiled about the locked 'wire rope with the coils inthe same direction as the outer layer of wire of the lockedcoil rope or opposite thereto.- f

The annexed drawingshow one .example of how my rope is made up.

Figure 1 is a section, Fig-2 side elevation, and Fig. .3 is a side elevation showing a portion of a locked coil wire rope and one of the iattenedl exterior strands applied thereto. v

In the embodiment of the invention shown in theaccompanyin drawing, A indicates generally the locke coil. wire rope and B the layer of iattened twisted strands covering the exterior thereof as shown clearly in Figs. 1 and 2. The locked coil wire rope is shown in Fig. 3 as built u of an interior or central roundvcore wire the layers D, E, F, G, H laid successivelyl upon onelanother in a spiral direction with reference-to the the locked coil wire rope.

exterior thereof. It is to be understood that in Fi 3 all but one of the flattened exterior stran s are removed in order to illustrate more clearly the form of each strand.

In constructing a rope in the manner described above, `the locked coil wire rope pre- Y sents a smooth or unbroken exterior surface against which the fiat sides of the flattened exterior strandsare laid, insuring minimum wear byfriction between the 4interior locked y'coil wire rope and the exterior strands, and

.it presents the advantage of providing a stranded rope containing an increased area of eectrve w1re and consequently increased strength -for a rope of a given slze and at I do claim as m invention and'desire to secure by Lettersv atent is The combination of a' locked coil wire rope presenting a relativelyv smooth unbroken exterior and an exterior layer of strands coiled about the locked wire rope, each of' said strands comprising a pluralit of wires twisted together and each strand eing fiat-v tenedwith one of its flat sides lying against the relatively smooth unbroken exterlor of In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
